Infinite wires extend infinitely in both directions, while semi-infinite wires have one fixed endpoint and extend infinitely in one direction. The distinction is crucial in physics, particularly in magnetic field calculations. An infinite wire creates a uniform magnetic field around it, while a semi-infinite wire generates a magnetic field that varies based on its fixed endpoint. Understanding these differences is essential for accurately applying concepts in electromagnetism. This clarification aids in grasping the implications of wire configurations in magnetic field studies.
